eventually need to be replaced. The iPod touch battery isn’t user replaceable; it can 
only be replaced by an authorized service provider. For more information, go to

Security Features

Security features help protect the information on iPod touch from being accessed  
by others.

You can set up a passcode that you must enter each time you turn on or wake up 
iPod touch.

Set a passcode:  Choose General > Passcode Lock and enter a 4-digit passcode,  
then enter the passcode again to verify it. iPod touch then requires you to enter  
the passcode to unlock it or to display the passcode lock settings.
For addition information about using a passcode lock, see “Passcode Lock” on  
page 114.
